This router mortise jig is finally coming around to looking like a working jig. It’s a swiss army knife of mortise jigs: 45 degree ledge, a 90 degree horizontal ledge that can travel 4” up and down, and can slide 4” left or right to make room for 90 degree vertical pieces. Still working out a middle vertical 16”x2” bar of wood for clamping, still gotta put stops in on the rear T-track, and still more to do.
This was my first time working with hardwood (scraps I had laying around) and first time doing rabbets and dado’s.
Lots of mistakes in building this simple structure, but it was a learning experience.
I cut out triangles and large areas for 2 reasons: make the dang thing lighter to move around, and for future F clamps if the need arises.

That’s a sweet jig! I always want to build great jigs, but I usually end up cobbling junk together just to get through it. One of these days, I’ll get around to building a real jig! Great job on it. Now, comes the best part… simple mortises!

egads. i’m so stupid. was about to jump in bed after my shower… and it hit me. the front sliding up and down piece is a mistake. instead…a rotating pie slice pivoting at one pivot top point. will give 12” of ledge support and ANY angle other than just 45 & 90. And, can use the same 2 clamps along one ledge for all angles. good thing i just used scrap 3/4” ply for my rough draft.

Have your say...
